The A-NET project has designed and implemented a parallel object-oriented language, called A-NETL, and its processing systems. The systems have been implemented on three platforms, such as the A-NETL oriented multicomputer, a workstation cluster, and a commercially available parallel machine, AP1000.Based on the results of the implementations, this research has designed and evaluated the A-NET multicomputer, using system-on-chip(SOC)technologies. Thus, the research includes the followings : (1)the evaluation of the various A-NETL implementations as the base of the research, (2)the design and evaluation of a multi-threaded, node processor architecture, (3)the design and evaluation of a new adaptive, router architecture, called Recover-x, (4)the SOC multicomputer architecture of the year 2005, and(5)the applications of the A-NETL multicomputer to various areas.The results of these research indicate that(1)the SOC multicomputer is a promising architecture for future parallel machine, (2)the router should be included in an SOC node, and(3)there is a trade-off point between on-chip DRAM capacity and on-chip cache one.
